packages instead of dropping files in a directory (eg. rpm can tell you 
when the package was built, installed, what it contains, etc), even if 
it's only on one node. RPMs are easy to install, reinstall, remove, 
update, etc.

Attached is a small script I wrote to automatically package software that 
didn't come with a spec file. Typical use:

$ cd foo-0.1
$ ./configure --prefix=/usr
$ make
$ make install prefix=/tmp/foo-0.1/usr
$ mkrpm.sh
usage: mkrpm.sh [options] /path/to/<package>-<version>
         -p <package name>       specify rpm package name
         -v <package version>    specify rpm package version
         -r <package release>    specify rpm package release
         -k                      package is a kernel
         -d <file>               package description
$ mkrpm.sh /tmp/foo-0.1

(The script can deduce the name and version from the directory name.)

Of course it needs a suitable environment for building RPMs.
Not tested with MPICH, but it should work just as above.


Cheers,
